CYLINDER-HEAD.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application led January 3051907. Serial No. 354.863.

To all whom it may concern:

Be it knomi that I, HENRY A. BUCK, a citi- Zen of the United States, residing at the city of Providence, 'in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Sheet-Metal Cylinder-Heads, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in the construction of cylinder heads, covers and the like, and has for its object to provide a cylinder head or cover that is constructed of sheet or plate metal the same being particularly adapted for use on pump and engine cylinders but serving equally well as a cover or head for receptacles of any kind in which heavy pressures of liquids or gases may be required to be confined.

The particular feature of this invention is that these heads are constructed entirely of sheet or plate metal either steel or of any other suitable material capable of being stamped, pressed or swaged by suitable dies orpunches into the desired shape.

Another feature of the invention is that this head is constructed of a plurality of vplates arranged and formed to reinforce 'and support each other in such a manner as to give great strength to the construction.

My improved cylinder head has many advantages over the old form of cast-iron heads, among others being, first, the increased strength of construction which is, to say the least, over three times that of any form of casting second, great saving in weight 5 third, great increase in the elasticity, the possibility of breakage being reduced to a minimum; fourth, economy in cost of construction, as has been proved in practice, a cylinder head formed with punches and dies can be roduced complete for much less than woul be the cost of the cheapest casting of the same diameter, without considering the expense of finishing the same, fth, economy of time in manufacture. The various stampings or parts can be manufactured, assembled and finished in less time than it requires a workman to set the work and take one chip across the face of an ordinary cast head of equal diameter. Then again, when the parts are constructed by die work they are all perfectly true and may be exactly duplicated, all the parts being thus rendered interchangeable. The quality of the material and the manner in which the head is constructed renders the same practically indestructible.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this s ecication in which similar characters of re erenoe indicate corresponding parts in all the views.

In the accompanying drawings: Figure 1- is a sectional view showing a form of cylinder head adapted to allow the piston rod or driving shaft to pass therethrough, the same being constructed entirely of sheet material. Fig. 2-is a detail showing the outer head plate in section. Fig. S-is a detail showing the inner head plate in section. Fig. LI-is a detail showing the binding nut in section. Fig. 5-is a detail showing the binding collar in section which is adapted to be screwed into said binding nut for the purpose of firmly securing the center portion of the head together and forms a bearing therein. Fig. 6- is a detail in section of the packing gland. Fig. 7"shows a portion of a cylinder and a modified form of head where the inner plate is plain, an intermediate bracing plate being located between the inner and outer plates7 and showing the center portion of said outer plate turned inward onto the intermediate plate to support, strengthen and stiifen the whole. Fig. S-shows a detail in section of an intermediate reinforcing or bracing plate.

Referring to the drawings the inner head plate 1 is preferably cut in the form of a circular disk from sheet material an annular flange 2 being formed thereon by pressing upward or raising the circular flange portion thereby forming the lip 3 which is adapted to fit closely into the end of the cylinder 24, as shown in Fig. 7. To form the construction illustrated in Fig. I the center portion of this plate is pressed outward from the inner face ofsaid plate providing a'central circular aperture A around which is formed the annular flange collar 5, which collar serves as a center support and greatly increases the strength of the plate. The outer head plate 6 is also provided with a flange ortion 7 raised from its outer face, the stoo being'preferably carried around in a circular form, as shown at 8, to increase the strength and at the same time lend grace and beautyto the design. The face of this flange 7 corresponds in size and is adapted to register with the flange 2 of the inner plate l. The center portion of this outer plate is like plate 1 swaged inward providing an aperture 9 around which is formed the annular flange collar 10. The-inner diameter of this collar 10 is made a trifle less than the outer diameter of the flange collar 5 so that when these outer and inner head plates are brought together their center portions must be forced one Within the other thereby providing a true central bore surrounded by a metal wall of double thickness. Through the anges of these plates may be y punched as many bolt holes 25 as desired.

' from its opposite end.

At 11 is a tubular binding collar, also constructed of sheet material, and having a shoulder or head 12 turned or pressed outward at one end .and being threaded at 13 for a portion of its length on its outer surface At 14 is a binding nut also pressed up from sheet material having a shoulder or flange 15 at its outer end and having its opposite end flared or-turned outward at 16 so as to receive a more perfect bearing where it comes in contact with the upper surface of the o uter plate, the inner surface of this nut being threaded at 17. At 18-18 are tapped holes in said 'fla-nge into which the packing gland studs 19-19 are screwed. y

In order to secure the outer head plate and the inner head plates permanently together the binding collar 11 is adapted to fit tightly in and is forced through the center bore 4 of the head from the inside outward and onto its outer end is screwed the binding nut 14 thus securely locking the two heads tightly together rendering the joint absolutely steam tight. The packing. gland 2O may also be made of sheet metal and is provided with al flange 21 through which the holes 22 are formed for the reception of the gland studs 19, the body portion of this gland being adapted to iit closely into the bore of the binding collar, as shown in Fig. 1. Into this gland may be forced a removable and renewable bearing bushing 23 which may be formed of any suitable journal metal. A bushing 24 of a similar character may also be forced into the opposite end of the binding collar 12 the whole forming a bearing for a shaft of a simple and practical construction packed with a suitable stuffing boXI A feature of my improved construction isv that the head being constructed of a plurality of plates may be formed hollow providing a chamber between the plates, as illustrated in Figs. 1- and 7. This chamber may serve either as a cooling or heating jacket by receiving a circulation of either water or steam. In or'der to provide an inlet and outlet to this hollow head the outer plate 6 may be swaged outwardas at 26 and a nipple 27, threaded at its outer end, is forced into the aperture and expanded therein to form a steam tight fit, and if it is de` sired to pass the contents of the head into the cylinderI suitable apertures, not shown, may be made in both the inner head plate 1 and the intermediate brace plate 2S. ln order to stiffen the head any number of brace plates may be formed to fit into the interior of the head between the inner and outer plates and arranged in any convenient i manner, and where the surface of the inner plate 1 is plain, as shown in Fig. 7, the plates may all be securely locked together by means of the cylinder head bolts 29 placed at close intervals around the flange.

My invention is not restricted to the construction and arrangement of parts herein shown and described nor to the various details thereof as a head constructed in any form of a plurality of plates of sheet material arranged to reinforce and support each other would come within the spirit and scope of my invention, one practical embodiment of which has been herein illustrated and described without attempting to show all the various forms and modifications in which my invention might be embodied.`
